cervinho blast freezer/chiller problems

[1mikeefc1]

Hi to all just wondering if anyone has had much experience on ital cervinho blast freezer/chiller.
Can't find any information on fault codes anywhere.
The cabinet I'm working on was tested as follows-
-bowl of hot water in (65 degreescelcius)
-food probe into bowl
-initiated blast chill

all worked ok for about 20 minutes temp went down to 10 degrees then all of a sudden the cabinet shut down and was showing minus 24 degrees. Checked inside with my probe and it was at 10 degrees.
I have since changed the food probe but the same thing keeps happenig.

Help would be much appreciated thank you.

What controller they are use?

the controller has no model or any markings on it at all and is unlike any other i have seen.
it also doesnt look like it can be replaced.

Based on what you saying, it is possible that you have some bad electrical contact in wiring of probe , or controller is faulty.

Thanks for the advice. As I have changed the probe and the controller won't come out I will check all connections and if still persists then the catering supplier can change the cabinet.
